ubuntu14.04 安裝mysql 失敗經歷（Access denied for user 'root'@'localhost' (using password: YES)）
# mysql -uroot -p
輸入密碼：
-----》Access denied for user 'root'@'localhost' (using password: YES)
# cat /etc/mysql/debian.cnf
[client]
host = localhost
user = debian-sys-maint
password = hxhbsi8z7QApavYe
socket = /var/run/mysqld/mysqld.sock
[mysql_upgrade]
host = localhost
user = debian-sys-maint
password = hxhbsi8z7QApavYe
socket = /var/run/mysqld/mysqld.sock
basedir = /usr
# mysql -u debian-sys-maint -p
輸入密碼：hxhbsi8z7QApavYe
Access denied for user 'debian-sys-maint'@'localhost' (using password: YES)
# mysql
只有一個數據庫
-----》information_schema
# SET PASSWORD FOR 'debian-sys-maint'@'localhost' = PASSWORD('hxhbsi8z7QApavYe');
# mysql -u debian-sys-maint -p
輸入密碼：hxhbsi8z7QApavYe
按照網上說的做了 啊 還是不行
最後找到 my.cnf
[mysqld]
#
# * Basic Settings
#
user = mysql
pid-file = /var/run/mysqld/mysqld.pid
socket = /var/run/mysqld/mysqld.sock
skip-grant-tables
port = 3306
basedir = /usr
datadir = /var/lib/mysql
tmpdir = /tmp
lc-messages-dir = /usr/share/mysql
skip-external-locking
發現三個資料庫
# use mysql;
# update user set password=PASSWORD("rootadmin") where user='root';
註釋掉
[mysqld]
#
# * Basic Settings
#
user = mysql
pid-file = /var/run/mysqld/mysqld.pid
socket = /var/run/mysqld/mysqld.sock
#skip-grant-tables
port = 3306
basedir = /usr
datadir = /var/lib/mysql
tmpdir = /tmp
lc-messages-dir = /usr/share/mysql
skip-external-locking
重啟MySQL服務
